Just got my 5x today, and it does "rapid charging" when I connect with the charger in the box, but when I connect using other USB cables/plugs (one supports QC 2.0, the other is a regular charger but supports 2.1A charging), I get a message that the device is "Charging slowly."
Are there other certain specs that a cable or charger has to have to take advantage of rapid charging?
